Hi, I am looking for help with the following problem.

I have located one corner of my property marked by "monument".
My Garmin ETrex Legend (connected to my laptop running Streets and
Trips) shows the following coordinates of this point:

Example:
41.70816 N
73.83263 W

Now my survery states that from this point I have to go:
S21 00 12 E - 553.34'

Using this information: how do I compute the coordinates of this point?
In this format? (Decimal I guess it's called). I am sure there must be
some formula I could use.

thank you in advance

here are some Google key words

state plane coordinates latitude longitude rectangular polar

a simpler solution might be to use the gps navigate function from your
existing corner and use
built in compass and distance ( I don't know the particulars of the etrex)

553/5280 = 0.105 miles

Search on Forward and Inverse.

Using a program I have by Mentor Software and Ellipsoid WGS84 I got the
following:

41.70675 N
73.82187 W

It is important to keep in mind several things:
First and foremost the accuracy of your handheld GPS unit
many recreation grade units have accuracy's in the tens of
meters.
Second, your little gps unit is giving you Latitude and Longitude
You have no way of knowing if the survey data is on any standard
"datum" Many surveys , especially in the Colonial States use a
arbitrary basis of bearings.

No! You are quite mistaken

A program is never finished until the programmer dies.

The statement above was quite correct. A single-point, recreational reciever
is fortunate to be accurate below 20 meters.

My Garmin CSx60 is accurate unto 3 meters and less, depending on the
reception of the satellites signals
